bundler错误地尝试安装“开发”和“测试”生产中的群体宝石 [英] bundler incorrectly trying to install "development" and "test" group gems in production

问题描述

我有一个小型的网络应用程序，它使用了一堆宝石。其中一些仅用于 test 和开发环境。现在，当我尝试使用以下命令在生产服务器上启动独角兽时，它将失败。

  unicorn_rails -E生产-D -c config / unicorn.rb 
  

我在日志文件中看到的错误是：

 刷新宝石列表
找不到宝石'spork（> = 0.9.0.rc2，运行时）'您的Gemfile中列出的宝石来源。 
尝试运行`bundle install`。 
  

我粘贴了下面的gemfile：

  source'http://rubygems.org'
 
 gem'rails'，'3.0.1'
 gem'独角兽'
 gem'mongoid'，'> = 2.0.0.beta.19'
 gem'devise'
 gem'cancan'
 gem'haml'，'> = 3.0.0 '
 gem'bson'
 gem'bson_ext'
 gem'formtastic'
 gem'bluecloth'
 
 group：production do 
 gem 'capistrano'
 end 
 
 group：开发do 
 gem'haml-rails'
 gem'hpricot'，'0.8.2'
 gem' ruby_parser'，'2.0.5'
 gem'less'
 gem'rspec-rails'，'> = 2.0.1'
结束
 
组合：开发，：test do 
 gem'spork'，'> = 0.9.0.rc2'
 gem'mongoid-rspec'
 end 
 
 group：test do 
 gem'factory_girl_rails'
 gem'autotest'
 gem'cucumber-rails'
 gem'cucumber'
 gem'capybara 
 gem'shoulda'
 gem'database_cleaner'
 gem'test_notifier'
 gem'rspec'，'2.0.1'
 gem'launchy'
结束
  

Bundler应该检测正确的环境并忽略其他宝石，对吗？现在，我删除了所有不在服务器上的默认组中的行，以使其工作，但这是一个丑陋的黑客。

解决方案

经过大量的挖掘，我找到了解决这个问题的方法。我所要做的就是在启动服务器之前运行 bundle install --without development test 。这会在rails根目录中添加一个 .bundle / config 文件，其中 BUNDLE_WITHOUT：test：development 。现在，无论何时运行捆绑安装或启动服务器，它都会忽略这些组。

从文档

Bundler CLI允许您指定
a列表，其中gem bundle
install不应该使用
--without选项进行安装。要指定多个要忽略的组，请指定由空格分隔的
组列表。

捆绑安装 - 无测试捆绑
安装 - 无出局开发测试
在运行软件包安装 - 没有执行
测试之后，bundler会记住您在最后一次
安装中排除了测试组的
。下次运行
bundle install时，如果没有任何 - 没有
选项，bundler会记得它。

另外，调用Bundler.setup没有
参数，或者调用require
bundler / setup将设置所有组
，除了通过
--without排除的那些（因为它们显然不可用）。

I have a small web app, which uses a bunch of gems. Some of them are only used for test and development environments. Now, when I try to start unicorn on the production server using the following command, it fails.

unicorn_rails -E production -D -c config/unicorn.rb

The error I see in the log files is:

Refreshing Gem list
Could not find gem 'spork (>= 0.9.0.rc2, runtime)' in any of the gem sources listed in your Gemfile.
Try running `bundle install`.

I've pasted my gemfile below:

source 'http://rubygems.org'

gem 'rails', '3.0.1'
gem 'unicorn'
gem 'mongoid', '>= 2.0.0.beta.19'
gem 'devise'
gem 'cancan'
gem 'haml', '>= 3.0.0'
gem 'bson'
gem 'bson_ext'
gem 'formtastic'
gem 'bluecloth'

group :production do
  gem 'capistrano'
end

group :development do
  gem 'haml-rails'
  gem 'hpricot', '0.8.2'
  gem 'ruby_parser', '2.0.5'
  gem 'less'
  gem 'rspec-rails', '>= 2.0.1'
end

group :development,:test do
  gem 'spork', '>=0.9.0.rc2'
  gem 'mongoid-rspec'
end

group :test do
  gem 'factory_girl_rails'
  gem 'autotest'
  gem 'cucumber-rails'
  gem 'cucumber'
  gem 'capybara'
  gem 'shoulda'
  gem 'database_cleaner'
  gem 'test_notifier'
  gem 'rspec', '2.0.1'
  gem 'launchy' 
end

Bundler is supposed to detect the right environment and ignore the other gems, right? Right now, I am deleting all the lines which are not in the default group on the server to get this working, but that's an ugly hack.

解决方案

After a lot of digging I found the fix for this issue. All I had to do was run bundle install --without development test before starting the server. This adds a .bundle/config file in the rails root with the line BUNDLE_WITHOUT: test:development . Now whenever you run bundle install or start the server it'll ignore those groups.

From the documentation

The Bundler CLI allows you to specify a list of groups whose gems bundle install should not install with the --without option. To specify multiple groups to ignore, specify a list of groups separated by spaces.

bundle install --without test bundle install --without development test After running bundle install --without test, bundler will remember that you excluded the test group in the last installation. The next time you run bundle install, without any --without option, bundler will recall it.

Also, calling Bundler.setup with no parameters, or calling require "bundler/setup" will setup all groups except for the ones you excluded via --without (since they are obviously not available).
